The purpose of this study was to examine visual selective attention strategies of elite wheelchair (WC) tennis players. As an extension of research, elite able-bodied (AB) tennis players were examined and as a second research extension, a new piece of equipment, not previously used in sport, the Eye-gaze Response Interface Computer Aid (ERICA) was utilized. A total of 32 WC and 31 AB tennis players participated in this study. All participants had current world rankings. Participants watched a video of a professional tennis player serving and imagined competing in a match against the player as eye movements were recorded by the ERICA system. The ERICA system was noninvasive and found to be highly reliable (r = 0.92). During the ritual phase of the serve, results revealed WC players either predicted the tossing area ahead of time (the WC Predictive group) or focused on the non-dominant tossing arm (the WC Real Time group). During the preparatory/execution phase the WC Predictive group focused on the non-dominant arm, while the WC Real Time group focused on the arm, racquet and shoulder area. After ball/racquet contact WC players focused on the ball. AB players focused on the non-dominant arm during the ritual and preparatory phases then the arm, racquet and shoulder region during the execution phase and after ball/racquet contact focused on the ball for the longest period of time. These results are a step in the process of developing knowledge to educate and create intervention strategies for tennis players of all skill levels, AB and disabled, to improve performance when playing tennis.Subjects--Topical Terms:
